To edit the paid invoice, you can go to the Finance – Payment section and void that payment record, and then the invoice’s
status will be changed into Not paid.

When the invoice status is updated, you can edit the invoice amount from the
Finance – Invoice section and can update the payment status as Paid with the correct amount.

Notably, when you voiding the payment, please make sure you’re disabling the notification, and the void payment records will
stay in the Finance – Payment section.
